Is it ok to call forward from the close() method in a custom UDTF? I have a
custom UDTF that does that
and it works fine with Hive 9. The UDTF needs to emit a few rows after
processing all the input rows. So it collects the rows in the process()
method and processes them in the close() method and outputs a few rows. Can
it cause problems in the later versions of Hive?
